Adding a point to a label will automatcillay make it 'mute'. 1 point = 'point' label (point position, normal, color, etc.) 2 points = 'vector' label (vertices position, distance) 3 points = "triangle/plane' label (vertices position, area, normal)

false if 'full'
bool cc2DLabel::fromFile_MeOnly ( QFile &  in,
short  dataVersion,
int  flags 

Loads own object data.

Called by 'fromFile' (recursive scheme) To be overloaded (but still called;) by subclass.

Member Data Documentation

int cc2DLabel::m_labelROI[4]

label ROI

ROI is displayed relatively to m_screenPos (projected in displayed screen space). m_screenPos corresponds to its top-left corner. So ROI[1] is the distance to the upper border and ROI[3] is the distance to the lower border (relatively to m_screenPos).

float cc2DLabel::m_screenPos[2]

close button ROI

Label position (percentage of screen size)
